As far as I know the answer is no. The render layers are simply there to split out the different elements of the render e.g. diffuse, spec, ambuient etc. You want these to be the same so that when you line them up in cmop there's no discrepancies.
To get what you want you would need to save out different scene files I would think. I could be wrong I dont use render layers in maya much
